LEVER TRACK-JACK.

SPECIFICATION forming part of Letters Patent No. 491,049, dated January31, 1893.

' Application filed May 4. 1892- Serial No. 431.848. (N0 model.)

To all whom it may concern.-

Be it known that I, JOHN HENRY, a subject of the Queen of Great Britain,and a resident of Ilderton, in the Province of Ontario, Canada, haveinvented a certain new and useful Lever Track-Jack, of which thefollowing is a full, clear, and exact description.

In the accompanying drawings, of this invention. Figure 1. is a frontview, and Fig. 2. is a side view. Fig. 3. is a detailed side view of thesocket bracket and dogs, showing the latter disengaged from thestandard. Fig. 4. is a side view of this invention, the weight andupright at one side being removed, and a cen tral section of thebed-plate being shown, in order to more clearly show the working partswhen in operation. Fig. 5. is a detail perspective View of the pivotalsocket bracket.

A, designates a bed-plate, formed with the opening, a. Y

B, B, designate uprights, rigidly secured to, or formed integral withbed-plate, A. The connection between the uprights, B, B, and bed-plate,A, is further strengthened by the braces, b, and in the adjacent sidesof these uprights, B, B, grooves, O, are formed.

D, designates a sliding standard formed with the foot, n, which standardis slidingly supported in the grooves O, of the uprights, B, B d, arerecesses, formed in the standard, D, as shown.

E, is a fulcrum, secured to the uprights, B, B, on which the lever, F,rests, when engaging with the recesses, cl, this fulcrum, E, also bracesand assists in strengthening the uprights, B, B, at their upper ends.

G, G, designate dogs of varying lengths, and these dogs are pivoted onthe pivot bolt, e.

H, is a socket arm, through which the dogs, G, extend.

I, is a shaft, which is supported perfectly free in one of the uprights,B, to theinner end of which shaft, I, the socket arm, H, is rigidlysecured, and with this shaft, I, said socket arm, H, moves.

J, is a crank, which may be secured to, or it may be an extension formedintegral with the shaft, I, to which crank, the weight, K, is pivotallysecured.

L, is a handle, which forms a convenient means for transporting thisimplement from one place to another; and M, is a railroad rail.

The opening, a, is formed in the bed-plate, A, to permit the standard,D, and foot, n, to be lowered therein, so that the upper face of thefoot, n, will be about flush with the upper face of said bed-plate, inorder to readily insert the bed-plate, A, and foot, n, underneath therail. This opening, a, also permits the sand or gravel to be readilyremoved, to prevent it from interfering with the lowering of thestandard, or the operation of the dogs. And dogs of varying length areused, in order to hold the standard and rail at the position to whichthey are adjusted, and to give a fine vertical adjustment of the rail,so as not to raise the latter higher than is absolutely required,,in

order to bring it up to the required height.

The action of the weight, K, and socket arm,

being connected with the socket arm, H, the

latter is also adjusted to the positions corresponding thereto, thepositions of the socket arm, H, being shown in Figs. 3'and 4:. Byadjusting the weight, K, to the position shown by solid line in Fig. 2.the dogs, G, and socket arm, H, will be adjusted as shown in Fig. 4.that is, with one of the dogs engaging with the recess in standard, D,to rigidly and safely hold the latter, at the elevation to which it maybe adjusted; and by adjusting the weight, K, to the position shown bydotted line in Fig. 2. the socket arm and dogs are adjusted to theposition shown in Fig. 3., that is disengaged from the recesses, d, instandard, D. In the former case, the upper side, 9, of the socket arm,H, abuts against the back of the dogs to hold them, or look them incontact with the recesses, d, in the standard, D, and in the lattercase, the arm, g, prevents the dogs from falling down in a horizontalposition, at the same time, the side, h, of the socket arm, H, preventsthe dogs from accidentally engaging with the recesses, d, in thestandard, D.

The operation of this invention is very simple and is as follows ;'-Thebed-plate, A, is inserted between the ties under the rail, until therail, M, and foot, h, are in the position shown in Fig. 2.The weight, K,is then adjusted to the position shown by solid line in Fig. 2. thelever, F, is then placed on the fulcrum, E, and the end engaged with therecesses, d, in the standard, D, as shown in Fig. 4. and by pressingdown on, and lowering the outer end of said lever, F, the inner end andstandard, D, will be raised, until the ties and rail, M, are raised tothe proper height, the ties are then packed with sand and gravel, tohold them and the rail in this position, this packing of the ties withgravel eases the down- Ward pressure, of the rail, M, on the foot, n,and the downward'pressure of the standard, D, on the dogs, G,so thatwhen the ties are properly ballasted the weight, K, may be readilyadjusted to the position shown by dotted line in Fig. 2. and the socketarm and dogs to the position shown in Fig.3. When adjusted as justdescribed, the standard, D, is lowered by its own weight, to theposition shown in Fig. 2. ready to be used again where required.

Having thus described my invention, I claim;'

A lever track jack, consisting of the bedplate, A, in which an opening,a, is formed, the uprights, B, B, having the grooves, 0, formed therein,the sliding standard, D, having recesses, d, formed therein, andprovided with a foot, n, in combination with the dogs, G, the socketarm, I-I, shaft, I, crank, J, and weight, K, substantially as shown anddescribed, and for the purpose specified.

In testimony whereof I affix my signature in the presence of the twoundersigned witnesses.

JOHN HENRY.
